Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed March 31, 1902. serial No; 100,671.

To all whom it may concern.-

Be it known that I, MAURIoE O. RYPINSKI,

' a citizen of the United States, residing at shown in Fig. 1 in the same direction.

Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Electric Railways, of which the following is a specification.

My invention relates to electric railways in which the energy is obtained from a third rail or conductor located either between or just outside the tracks and which is formed of sections normally disconnected from the source of supply, but rendered active by the appreaching car or train.

My invention consists of electromagnetic switches located in the connections between the sections of the third rail or conductor and the feeder and means for energizing and denergizing said electromagnetic switches, which means comprises auxiliary switches located adjacent the track-rail and operated by the passing car, said auxiliary switches being adapted to connect the ends of the coils of said electromagnetic switches either to ground or to the feeder.

- In the accompanying drawings, Figure 1 is a diagrammatic representation of my sectional third-rail system, showin the manner in which the sectional third rai is rendered active by a car passing over the line. Fig. 2 represents diagrammatically the same system, showing how the sectional third rail is rendered active by a car following the Fcar 1 3 is a sectional elevation of one form of mi; chanically-operated switch. Fig. 4 is a section on the line 4 4 of Fig. 3, and Fig. 5 is a section on the line 5 5 of Fig. 3.

Referring now to Figs. 1 and 2, F represents the feeder, R, R and R sections of third rail or conductor, which are made approximately the length of the car operating thereon, and S, S and S the electromagnetic switches for connecting the sectional conductor to the feeder. C represents a car carrying the motor M, and R the track-rails on which said carruns. In the system illustrated the track-rails are used as the return. Switches 8, s and s mechanically operated by a projection carried by the car, are located along the track, as shown, and serve to successively connect the operating-coils a, a and a of the electromagnetic switches one arm or ninety degrees at one time.

S, S and S in circuit with the source of supply. The coils a, a and a of the switches S, S and S are permanently connected together in series through the conductor 4 4, and the connections between adjacent coils are also connected, respectively, to the fixed contacts I) of the switches s, 8 and 8 through the conductors 2' 2, &c., as shown. The fixed contacts d of the switches s, 8 and s are connected to ground or the rail-return R through the conductors 3 3, 850., while the contacts 0 are connected directly to the feeder F through the conductor 1 1, &c. The movable contact 6 of each of the switches s, 8 and s is adapted to connect the contact I) with either of the contacts 0 or d, as desired.

In Figs. 3, 4, and 5 I have shown one form of the switch 8. The fixed spring-contacts b, c, and d of the switch are shown as mounted within the moisture-proof casing c. The contact I) is shown in Fig. 5 as divided into two parts electrically connected, as it would be much easier to manufacture in this form. Such a construction allows the movable contact-bar e to move freely between the fixed contacts. The contact-bar e is carried by the shaft p, which passes through the diaphragm d in the casing c and is rotatably mounted therein. Fixed on the upper end of the shaft is the star-shaped impact-receiving whee 70, which is maintained in the position into which it may be forced by the projection h, carried by the car, by means of the spring 07,, which is fixed to the protectinghood 0 which forms the upper part of the casing c. The spring a coacts with the arms of the star-shaped wheel successively and prevents said wheel from moving more than represents the traclcrail; w, a wheel of the car; R, the sectional third rail, and T the trolley or collector-shoe cooperating therewith. The switch-contacts can be readily removed from the casing a through the bottom of the casing c after removing the base- I plate 25.

that both sides of the coil (1 have been. 0011? nected to the railreturn, thereby denergizing the electromagnetic switch which connects the rail R with the feeder. The car in the position shown is taking current through the switch S the coil a of which has been energized by a current through the conductor 1 from the feeder F, through contact 0 of switch 8 movable contact e, contact I), conductors 2 and 4, coil a conductors 4 and 2 to contact b of switch 8 movable contact 6, contact d, conductor 3 to rail-return R. As the car moves forward the switch 8 is thrown into the position shown in Fig. 2, both sides of the coil a are grounded, the switch S opens by gravity, though it may be assisted in opening by means of a spring or the like, and the rail R becomes denergized, while the rail R becomes energized, as above described. The car shown in Fig. 2 has thrown the switches s and s from the position shown in Fig. 1 to the position shown in Fig. 2, thereby connecting both ends of the coil a to the feeder, deprlving the coil (1 of current and allowing the switch S to open. The rail R is energized by its connection to the feeder through the switch S, the coil a of which receives current from the feeder through the following circuit: conductor 1, contact 0 of switch 8 movable contact 6, contact 6, conductors 2 and 4:, coil a conductors 4 and 2, contact 6, movable contact 6, and contact (1 of the switch 8 the conductor 3 to the rail-return R. As the car moves forward the switch 5 is thrown into the position shown in Fig. 1, both sides of the coil a being connected to the feeder F, deenergizing the switch S and simultaneously energizing the switch S as above described.

While I have shown my invention as applied to a sectional thirdrail system, I do not limit myself thereto, since my invention is equally applicable to a surface or button contact system in which a long contact-shoe is carried by the car.

My invention is also applicable as a blocking system either on overhead trolley-roads or third-rail roads on which the third rail or trolley is divided into long sections, on each of which but one car or train is to be allowed at one time. Should a second train or car enter the block or section, both cars or trains would be deprived of current, as will be readily understood, for instance, by reference to Fig. 1. If a second car should enter the section occupied by the car 0, the switch 8 would be thrown so as to connect the end of the coil (1. controlled by said switch to the feeder, and since the other end of said coil is connected to feeder through the switch 3 no current would flow through the coil a After coming to a stop neither car nor train can move until one of the switches s 8 &c., controlling that block has been rotated ninety degrees by hand.
